BAR `PIIN AND TKETOD OF MAKING THE SAllaTE.

Application filed October 15, 1921. Serial No. 508,039.

To all whom t may concern.'

Be it known that we, FRED S. Minna and RALPH K. vMAKER, citizens of the United States, residing at Seekonk and Providence, in' the counties of Bristol and Providence. and States of Massachusetts and Rhode island, respectively,r have invented certain` new and useful Improvements in liar Pins i and hlethods' of Making the Same, ot which the following is a speciiication.

This invention relates to an improved bar pin and method of makingthe same7 and `more particularly a structure of this character which may be readily and easily formed from plate material and the parts quickly assembledto form a pin of pleasing appearance wherein ornamental stones are held in position andpositively held against becoming lost.

@ne object of the invention isto provide an improved method of forming devices ot' thisfcharacter wherein the several parts can be readily and quickly formed and easily assembled to provide La device of thischaracter having an attractive appearance.

` Another object of the invention' is to providean improved device of this character wherein ornamental stones are held in position and given theappearance ot being set in the surface or the material and-at the same time lso held in place as to prevent their becoming dislodged from the setting.

Another object of the invention is to provide a simple and easily constructed device of this character the parts of which may be `readily formed and easily assembled to form the stock is to be clit to form barsot the desired length.

Fig. 3 is `a perspective view of one of the portions into which thestock is cut after the gem seats have been formed therein.

Fig. d is a perspective view of the channel shaped member after openings have been termed in the sideand end portions and lugs cut out from the sides.

Fig. 5 is perspective view of the channeled member showing ornamental stones positioned in the openings in the base thereof and a holding plate positioned over the stones, one side of the channel shaped meniber being broken away to better illustrate thev position of the parts.

' pleted structure.

Fig. 8 is a top plan view ot the completed structure, and,

i ifig. 9 is a sectional view taken along the in the manufacture of bar pins and similar devices by methods heretofore employed considerable time and labor has been required to iiorn'i the bar and provide openings therein Jfor the reception oi" ornamental stones, and the operation of setting each stone` in the openings and bending portions of the metal thereover to hold the stones in place has required a considerable amount of skilled labor. Moreover in structures thus made the metal prongs tor holding the stones in place are liable to become bent and thus some or' the stones may eventually become loosenedA l'roin their setting and frequently be lost.

ln order to overcome -these diiliculties and y will be positively held-against becoming lost as well as to devise a structure which can be readily and easily constructed without requiring the use ot' highly skilled labor we have had recourse to the following method ot construction and arrangement or parts.

ln the method employed by us, we are V-and 4is first operated upon by cutting out portions of thesides 3 and 4 as indicated at 5 and 6 to form ends for the separate channel shaped members and the stock 1s then cut into sections as indicated by the line I, 4-4 in Fig. 2 ofA the .drawings to obtain..

a channel shaped member as shown in Fig. 3. '."Ihenmember thus formed is then` placed in a press or otherwise suitablyoperated =`u on .to cut out openings 7 in the base thereofoffrsuitableflsizeto serve as seats for the stoneswwhich are to be used and openings '8..a-re formed in thesides 3 and 4 as well i assimilar. openings 9 inthe ends 10. `The `orderinyyhich the openings 7 8 and 9 are formed is notfmaterial to the-formation of.

- the structurev andmay be varied as desired.

, Freferably simultaneously with the formation. of the openings 8 in the sides 3 and 4,-

outs `11. areiformed in the sides 3 and 4 to out thestock upon three sides of rectanglesA i of substantially equal area to the rectangular openings 8 andthe rectangular' lugs 12 i thus formed in the sides are driven in-` wardly*gslightlyhduring the cutting opera- .tion asindicated in Fig. 5. It will be notedy that in the presentinstance three of these .lugsareformedin each of the sides 3 and 4,A although a greater or less number may be formed as appears desirable, andthe rectangular' lugs thus formed are located 1n linewith and are ofsubstantially the same` size as the openings 8. After the channel shapedmember has been formed as above Vwdescribed, one lof the ends 10 is bent up #into contact with the adjacent ends of the sides 3 and 4 as shownin Fig. Sand ornamental stones 14 arev seated in the openings i 7 formedin the base ofthe channeled memopenings-7 `in the base of the member.

ber,v the stones being properly positioned toexpose the faces thereof vthrouglr thi holding plate 15 provided with a plurality of suitably spaced openings 16 formed therein isthen placed back of thestones 15 and so positioned that the rear portions of the ornamental stones willv register with and project into the openings 16 formed in the holding plate.

The lugs 12'being,` as `previously stated, only slightly bent inwardly from the sides 3 and 4, the plate 15 `may be laid directly yupon the stones,` there being suliicient clearance between the side edges of the plate 15 and the sides 3 and 4 to permitY the insertion of the plate. The structure is now preferably placed in a suitable'press or otherwise operated upon to press the lugs 12 farther inwardly into the position indicated in Figs. 7 and 9, thus engaging the plate 15 to prevent it from accidental dis4 placement while leaving suifficient` space between the plate 15 and the lugs 12 to permit the insertion of a back plate as will be hereinafter described.

The back plate 2Qis Vishaped .cross-section and is preferably .formed from a plane strip 21 by rolling the same as indicated in F igt, 6.- of vthe .,clra'xvings, although any other suitable or desired method of forming=theback .platemay be employed. The V-shaped stock is cut into suitabley lengths to form the back plates20 and a pin, `base 22 `Aandclasp 23 are secured to each, asnbyl soldering, to form the completed back plate. Av )in 24 is suitablyy mounted in the base 22 and is adapted to engageftheclasp-23 for scouring the bar pin to fabric as iswell known in-the art. The completed back plate is inserted into. the channel shaped member through the ,openl end portion thereof, as shown in Fig.` 7 of thel drawings, and forced inwardly beneath thelugs 12Ithus lpressing the back plate 15 firmly into engagement with the stones 14 and securely vholding all of the parts against separation.- "There remains `,only to bend up the end 10 through which the' back 4plate has been inserted to forin the completed structure as shown in Figs. 8 andA 9 wherein the stones are seated in the openings formed in thebase portion ofthe channeled member and engaged and held in position by the holding yplate while the backplate interposed `between the lugs 12 and the holding Iplate binds `the several parts securely in place. i p

It will be noted that `after the lugs 12 are bent down as shown in F igs; 7 and 9 of the drawings-the openings remaining Vconstitute with Y the openings 8 previously formed a series of .ornamental openingsextending throughout the sides ofthe chan-4- nel'shapedmember, Vand, these appreciably addto the ornamental appearance ofthe structure. l'The openings `9V 4formed inthe end portionsl 10 of the'channeled member' may, if desired, be dispensed with-to have the ends display unbroken plane surfaces to View. Inthe formationof the Vshaped back plate and the 'bending of the lugs4 l2, the lugs 12. may rbe bent down to form a `more acute angle with'the holding plate, as

shown in'F ig. 9 of the drawings, and the form of the back plate correspondingly modified to kbring theapex of the back plate into closer relationship with the base of the stones.

le preferably provide an ornamental surface `for the exposed faceof the ychannel shaped member,-as; illustratedin Fig. 8 of the drawings, comprising an ornamental border 25, a bevel portion`26 and ornamental depressions 27 to simulate the appearance of a surface set pin.

l/Vhile we have described our improved structure and our preferred method'of inaking the same with considerable particularity in order to make clear to those skilled in the art the series of steps which may be employed, we are aware that various equivaient steps'in the mode of operation may be substituted for those herein described, and that certain modifications in the structure may be made without departing from the spirit and scope of our invention, therefore we do not desire or intend to be limited to the precise steps or sequence of steps described herein nor to the precise details of construction shown and described except as the same may be properly included within the scope of the appended claims when broadly construed in the light of our invention.
